摘要：The main objective of this research is to diagnose the environment of the Macta marshes located in Northwestern Algeria by taking into account their wealth and ecological functioning as a site of importance for Mediterranean biodiversity. This study is aimed in particular at managers of remarkable sites and those interested in the protection of the environment in Algeria. The methodology adopted is based on a spatiotemporal analysis of climatic and hydrologic data as well as on physicochemical analyses of surface water The results obtained demonstrate a long-term risk of the marshes desiccation and pollution by a concentration of high nitrates and phosphates, and high dissolved oxygen levels that induce eutrophication, as well as higher BOD5 values that indicate a high organic load. The follow-up of the organic pollution index "OPI" shows that the water of the Macta marshes is heavily polluted due to untreated domestic and industrial wastewater discharges as well as the intensive use of fertilizers which threaten the different habitats and the ecological functioning of this ecosystem.
